A Florida commercial shuttle is designed for 16 people, including its driver. Does its seating capacity meet Florida’s passenger-CMV threshold?
Correct answer: Yes, because the threshold is more than 15 people including the driver
Florida’s passenger-capacity threshold counts the driver and uses the vehicle’s design capacity, not the number aboard that day. The appropriate CDL class and passenger endorsement are required unless an exemption applies.
